Cardiovascular diseases (CVDs) are the leading cause of death worldwide, with atherosclerosis serving as a primary factor in their development. Platelets, leukocytes, and their interactions play a crucial role in initiating and amplifying atherosclerosis. This study aims to evaluate the levels of platelet-monocyte aggregates (PMA) and specific integrins involved in leukocyte recruitment, including macrophage-1 antigen (Mac-1) and lymphocyte functionassociated antigen-1 (Lfa-1), in patients with acute coronary syndrome (ACS).
